Title (EN) CIRCUIT PROTECTION CIRCUIT AND METHOD, AND POWER SUPPLY CABLE
(FR) CIRCUIT ET PROCÉDÉ DE PROTECTION DE CIRCUIT, ET CÂBLE D'ALIMENTATION ÉLECTRIQUE
(ZH) 一种线路保护电路、方法及供电线缆
Abstract:
(EN) Disclosed is a circuit protection circuit, comprising: a first protection monitoring circuit, a first switching circuit, and a self-recovery protection circuit with impedance changing with a temperature change. The first protection monitoring circuit is used for obtaining a first voltage difference between both ends of the self-recovery protection circuit, and outputting a first off signal to the first switching circuit when the first voltage difference exceeds a first preset protection voltage difference threshold. The first switching circuit is used for turning off the current output by a power supply when receiving the first off signal. Also disclosed are a circuit protection method, another circuit protection circuit, and a power supply cable.
(FR) L'invention concerne un circuit de protection de circuit, comprenant : un premier circuit de contrôle de protection, un premier circuit commutateur, et un circuit de protection à autodépannage dont l'impédance change lorsque la température change. Le premier circuit de contrôle de protection sert à obtenir une première différence de tension entre les deux extrémités du circuit de protection à autodépannage, et à émettre un premier signal de coupure du premier circuit commutateur lorsque la première différence de tension dépasse un premier seuil de différence de tension de protection. Le premier circuit commutateur sert à couper le courant transmis par une alimentation électrique lors de la réception du premier signal de coupure. L'invention concerne également un procédé de protection de circuit, un autre circuit de protection de circuit, et un câble d'alimentation électrique.
